"She has terrible migraine headaches. And they put her out of
commission for a day or more at a time. They come out of nowhere,
and they’re unpredictable,” a Bachmann adviser involved in

A spokeswoman for Bachmann, Alice Stewart, confirmed ”she
suffers from migraines and they’re under control with medicine,”
but said the report that they were incapacitating is wrong.

The sources reportedly came forward because they are "terrified
about the impact the condition could have on Bachmann’s
performance if she actually became president."
